Admit it, you’re addicted to collecting the Panini World Cup stickers. You’ve bought tons of packs and now you’re turning to friends in order to trade for those specific players you want in your album. Keeping up with all the stickers can be difficult though, and flipping through you album to see who you need can really slow down the trading process.

Enter the Panini Collectors app on iOS and Android devices. This free app has been crucial in my quest to fill my sticker album. Its key feature is the “Scan Stickers” option that lets you hold your phone’s camera to a sticker to catalogue it. The whole process is really smooth and easy to work with. A simple tap of your finger and the app records your sticker. You don’t even have to have particularly steady hands, as the app will recognize a sticker from close-up, sideways, upside down, and anyway you orient your phone as you speed through cataloguing your players. Once scanned, you can then search by country to see what stickers you own. It will even allow you to scan the same type of sticker multiple times so you know how many you have, which is crucial when it comes to trading.

Of course, the most addicting feature is the “Got,” “Need,” “Swap List” page. Here, the app records how many stickers you have, how many you need, and your completion percentage. It will even give you medals for every quarter of the album you complete. The interface is nothing fancy, but it adds that much more fuel to the fire of collection.

Download this app now and start scanning your album into it. It’s a quick way to reference what you have and what you need while you’re on the go. The app is available for free on iOS and Android.
